1 Sample configuration file for the Samba suite for Debian GNU/Linux. This is the main Samba configuration file. You should read the smb.conf(5) manual page in order to understand the options listed here. Samba has a huge number of configurable options most of which are not shown in this example Any line which starts with a ; (semi-colon) or a (hash) is a comment and is ignored. In this example we will use a for commentary and a ; for parts of the config file that you may wish to enable NOTE: Whenever you modify this file you should run the command "testparm" to check that you have not made any basic syntactic errors. ======================= Global Settings ======================= [global] Browsing/Identification Change this to the workgroup/nt-domain name your Samba server will part of workgroup =MSHOME server string is the equivalent of the NT Description field server (Samba, Ubuntu) server string = %h (Samba) Windows Internet Name Serving Support Section: WINS Support - Tells the NMBD component of Samba to enable its WINS Server ; wins support = no WINS Server - Tells the NMBD components of Samba to be a WINS Client Note: Samba can be either a WINS Server, or a WINS Client, but NOT both ; wins server = w.x.y.z This will prevent nmbd to search for NetBIOS names through DNS. dns proxy = no What naming service and in what order should we use to resolve host names to IP addresses ; name resolve order = lmhosts host wins bcast Networking The specific set of interfaces / networks to bind to This can be either the interface name or an IP address/netmask; interface names are normally preferred ; interfaces = /8 eth0 Only bind to the named interfaces and/or networks; you must use the 'interfaces' option above to use this. It is recommended that you enable this feature if your Samba machine is not protected by a firewall or is a firewall itself. However, this option cannot handle dynamic or non-broadcast interfaces correctly. ; bind interfaces only = true

2 Debugging/Accounting This tells Samba to use a separate log file for each machine that connects log file = /var/log/samba/log.%m Put a capping on the size of the log files (in Kb). max log size = 100 If you want Samba to only log through syslog then set the following parameter to 'yes'. ; syslog only = no We want Samba to log a minimum amount of information to syslog. Everything should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log through syslog you should set the following parameter to something higher. syslog = 0 Do something sensible when Samba crashes: mail the admin a backtrace panic action = /usr/share/samba/panic-action %d Authentication "security = user" is always a good idea. This will require a Unix account in this server for every user accessing the server. See /usr/share/doc/samba-doc/htmldocs/samba-howto-collection/servertype.html in the samba-doc package for details. security = user You may wish to use password encryption. See the section on 'encrypt passwords' in the smb.conf(5) manpage before enabling. encrypt passwords = true If you are using encrypted passwords, Samba will need to know what password database type you are using. passdb backend = tdbsam obey pam restrictions = yes ; guest account = nobody invalid users = root This boolean parameter controls whether Samba attempts to sync the Unix password with the SMB password when the encrypted SMB password in the passdb is changed. ; unix password sync = no For Unix password sync to work on a Debian GNU/Linux system, the following parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for sending the correct chat script for the passwd program in Debian Sarge). passwd program = /usr/bin/passwd %u passwd chat = *Enter\snew\sUNIX\spassword:* %n\n *Retype\snew\sUNIX\spassword:* %n\n *password\supdated\ssuccessfully*. This boolean controls whether PAM will be used for password changes when requested by an SMB client instead of the program listed in 'passwd program'. The default is 'no'. ; pam password change = no Domains Is this machine able to authenticate users. Both PDC and BDC

3 must have this setting enabled. If you are the BDC you must change the 'domain master' setting to no ; domain logons = yes The following setting only takes effect if 'domain logons' is set It specifies the location of the user's profile directory from the client point of view) The following required a [profiles] share to be setup on the samba server (see below) ; logon path = \\%N\profiles\%U Another common choice is storing the profile in the user's home directory ; logon path = \\%N\%U\profile The following setting only takes effect if 'domain logons' is set It specifies the location of a user's home directory (from the client point of view) ; logon drive = H: ; logon home = \\%N\%U The following setting only takes effect if 'domain logons' is set It specifies the script to run during logon. The script must be stored in the [netlogon] share NOTE: Must be store in 'DOS' file format convention ; logon script = logon.cmd This allows Unix users to be created on the domain controller via the SAMR RPC pipe. The example command creates a user account with a disabled Unix password; please adapt to your needs ; add user script = /usr/sbin/adduser --quiet --disabled-password --gecos "" %u Printing If you want to automatically load your printer list rather than setting them up individually then you'll need this ; load printers = yes lpr(ng) printing. You may wish to override the location of the printcap file ; printing = bsd ; printcap name = /etc/printcap CUPS printing. See also the cupsaddsmb(8) manpage in the cupsys-client package. ; printing = cups ; printcap name = cups When using [print$], root is implicitly a 'printer admin', but you can also give this right to other users to add drivers and set printer properties ; printer admin Misc Using the following line enables you to customise your configuration on a per machine basis. The %m gets replaced with the netbios name of the machine that is connecting ; include = /home/samba/etc/smb.conf.%m Most people will find that this option gives better performance. See smb.conf(5) and /usr/share/doc/samba-doc/htmldocs/speed.html for details You may want to add the following on a Linux system:

4 SO_RCVBUF=8192 SO_SNDBUF=8192 socket options = TCP_NODELAY The following parameter is useful only if you have the linpopup package installed. The samba maintainer and the linpopup maintainer are working to ease installation and configuration of linpopup and samba. ; message command = /bin/sh -c '/usr/bin/linpopup "%f" "%m" %s; rm %s' & Domain Master specifies Samba to be the Domain Master Browser. If this machine will be configured as a BDC (a secondary logon server), you must set this to 'no'; otherwise, the default behavior is recommended. ; domain master = auto Some defaults for winbind (make sure you're not using the ranges for something else.) ; idmap uid = ; idmap gid = ; template shell = /bin/bash ======================= Share Definitions ======================= Un-comment the following (and tweak the other settings below to suit) to enable the default home directory shares. This will share each user's home directory as \\server\username ;[homes] ; comment = Home de %U ; browseable = no By default, \\server\username shares can be connected to by anyone with access to the samba server. Un-comment the following parameter to make sure that only "username" can connect to \\server\username ; valid users = %S By default, the home directories are exported read-only. Change next parameter to 'yes' if you want to be able to write to them. File creation mask is set to 0600 for security reasons. If you want to create files with group=rw permissions, set next parameter to ; create mask = 0600 Directory creation mask is set to 0700 for security reasons. If you want to create dirs. with group=rw permissions, set next parameter to ; directory mask = 0700 Fin pour homes Un-comment the following and create the netlogon directory for Domain Logons (you need to configure Samba to act as a domain controller too.) ;[netlogon] ; comment = Network Logon Service ; path = /home/samba/netlogon ; guest ok = yes ; share modes = no Un-comment the following and create the profiles directory to store users profiles (see the "logon path" option above) (you need to configure Samba to act as a domain controller too.) The path below should be writable by all users so that their profile directory may be created the first time they log on ;[profiles] ; comment = Users profiles ; path = /home/samba/profiles

5 ; guest ok = no ; browseable = no ; create mask = 0600 ; directory mask = 0700 wins support = no [printers] comment = All Printers browseable = no path = /tmp printable = yes public = no writable = no create mode = 0700 Windows clients look for this share name as a source of downloadable printer drivers [print$] comment = Printer Drivers path = /var/lib/samba/printers browseable = yes read only = yes guest ok = no Uncomment to allow remote administration of Windows print drivers. Replace 'ntadmin' with the name of the group your admin users are members of. ; write list = A sample share for sharing your CD-ROM with others. ;[cdrom] ; comment = Samba server's CD-ROM ; locking = no ; path = /cdrom ; public = yes The next two parameters show how to auto-mount a CD-ROM when the cdrom share is accesed. For this to work /etc/fstab must contain an entry like this: /dev/scd0 /cdrom iso9660 defaults,noauto,ro,user 0 0 The CD-ROM gets unmounted automatically after the connection to the If you don't want to use auto-mounting/unmounting make sure the CD is mounted on /cdrom ; preexec = /bin/mount /cdrom ; postexec = /bin/umount /cdrom
